Question

std::string token, line("This is a sentence.");
std::istringstream iss(line);
getline(iss, token, ' ');

std::cout << token[0] << "\n";

This is printing individual letters. How do I get the complete words?

Updated to add:

I need to access them as words for doing something like this…

if (word[0] == "something")
   do_this();
else
   do_that();

std::string token, line("This is a sentence.");
std::istringstream iss(line);
getline(iss, token, ' ');

std::cout << token << "\n";

To store all the tokens:

std::vector<std::string> tokens;
while (getline(iss, token, ' '))
    tokens.push_back(token);

or just:

std::vector<std::string> tokens;
while (iss >> token)
    tokens.push_back(token);

Now tokens[i] is the ith token.
